To address finite-size effects in the use of the decay mutual information to characterize spatiotemporal chaotic dynamics, we modify the dispersion of the nonlinear Schrödinger equation to obtain a model system for which the number of unstable modes remains fixed while the domain size...

We analyze the effort allocation choices of incumbent politicians when voters are uncertain about politician preferences. There is a pervasive incentive to “posture” by overproviding effort to pursue divisive policies, even if all voters would strictly prefer to have a consensus policy...

This paper provides a theoretical and empirical analysis of the intrinsic preferences of state appellate court judges. We construct a panel data set using published decisions from state supreme court cases merged with institutional and biographical information on all (1,700) state supreme court...

Can machine learning support better governance? In the context of Brazilian municipalities, 2001-2012, we have access to detailed accounts of local budgets and audit data on the associated fiscal corruption. Using the budget variables as predictors, we train a tree-based gradient-boosted...
